A reliable, low-cost glass-mounted sensor is provided that does not use the current for generating electric field. The sensor includes a conducting transparent film (3) attached to a glass (2), a grounded frame (5) supporting the glass on the whole or part of the periphery, a support (4) insulating the conducting transparent film (3) from the frame (5), and a detector circuit for detecting the change in capacitance between the conducting transparent film (3) and the frame (5).
L'invention porte sur un détecteur monté sur verre économique et fiable ne nécessitant pas de courant pour produire un champ électrique et comprenant: un film (3) conducteur transparent fixé sur un verre (2), un cadre (5) à la masse (5) portant le verre sur tout ou partie de sa périphérie, un support (4) isolant le film (3) du cadre (5) et un circuit de détection des variations de capacité entre le film (3) et le cadre (5).
